Hard to tell from the photo if the external oil gallery plug (which has a square head, BTW) is just not installed, or if there's no hole for it. Photo of the casting date will tell that story.

  I can't comment on the correctness of this stamping but I wanted to say you can have a block decked and still retain the stampings providing the decking process doesn't take too much off vs. the depth of the stamp.Most original stampings will have a very-very slight ridge along the characters edge from the metal displacement of the imprint force. Any decking, providing it doesn't take the stamping totally off, will usually even out the slightly raised edge (as this photo looks) depending on the deck cut depth.

Look closely at the edges of the stamp, and you get the suggestion the feed lines actually roll downward into the lines of the stamp - to me, that indicates the stamping happened after the decking took place. The stamps should be sharp faced, which tends to not deform the material as much as standard character stamps do. Still, not saying this is definitively the case here, it only suggests it. If the block was decked only a few thousands, the stampings might survive intact, but in most cases it will lighten it up considerably (if not completely lift it).

I have a few V0425 DZ stampings and this matches exactly in terms of font and spacing. It looks ok to me.

I looked at a 70z this past summer and it had what appeared as the invoice number stamped on it in a couple places. I took a picture of the vin by the filter and it was pretty legible. I thought it was odd and the car had the wrong tach. I got home and blew the vin picture up and right beside the fresh one was the original so faint the owner had never seen it.  The real deal killer was it was supposed to be citrus green (ugh) and the car had not been in California near as long as the guy led us to believe..

I would like to share my observation of this block.  The reason they used a 618 block with a March casting will never be known, and very unusual.  I have an 05A car with vin 19n6401xx and a stamp of V0430DZ and a 010 block.  Two other examples of 05A are 19n6404xx with V0425DZ, 010 block; and 05A with vin 19n6403xx with stamp V0430DZ and a 010 block.  It looks like the block in question is completely out of wack with standard procedure.  It looks like the stamp date should, at least be in the first week of May with a vin in the 643 range.  There are several known examples with vin's in the 639 range, with a 010 block.  This block may be good, but the GM worker was drunk!

Thanks,
Bryan

 Considering there was no 'rotate stock' practice, I guess a block can sit on a shelf for a while before being pulled for assembly prep, or in a case of an assembled motor, sit on the rack for a while before getting installed and VIN stamped.
